• Most hens are productive layers for two years before declining in production, but some continue to lay eggs for several years.

• Hens will lay eggs whether or not they’ve ever seen a rooster. Roosters are necessary only for fertilization of eggs.

Egg development and laying process

• A female chick is born with thousands of tiny ova, which are undeveloped yolks. Once she reaches maturity, an ovum will be released into a canal called the oviduct and begin its journey of development.

• At any given time a productive hen will have eggs of several stages within her reproductive system. The eggs most recently discharged from the ovary are just tiny yolks, and the eggs farther down the oviduct are progressively larger and more developed.

• From the time an ovum leaves the ovary, it takes approximately 25 hours for the egg to reach the vent for laying. During that time period, the yolk will grow larger while being surrounded by albumen (egg white), wrapped in a membrane, and encased in a shell. Pigment is deposited on the shell as the last step of the egg production process.

• If sperm is present, the yolk will be fertilized before the albumen is deposited.

• As a chick embryo develops in a fertilized egg, the yolk provides nourishment and the albumen cushions the embryo.

• Although a hen has only one exterior opening (the cloaca or vent) for egg laying and elimination, eggs are not contaminated during the laying process. Two separate channels, the oviduct and the large intestine, open into the cloaca. As the egg nears the end of the oviduct, the intestinal opening is temporarily blocked off. The egg passes through the cloaca without contact with waste matter.

• The typical interval between eggs laid is about 25 hours, so a hen that lays an egg every day will lay a bit later each day.

• Hens don’t usually lay eggs in the dark, so once a hen’s laying cycle reaches dusk time, she will usually not lay till the following morning.

• Eggshell production drains calcium from the hen’s body. The comb, wattles, legs, and ear lobes will fade as the calcium leaches out.

Calcium must be replenished through either feed containing calcium, supplements such as oyster shell, or high amounts of calcium in the soil of birds with outdoor access.

Egg variations
• Young pullets often lay malformed eggs before getting established in a normal laying routine. Older hens may occasionally lay abnormal eggs due to age, stress, or illness.

• Pullet eggs--the first ones produced by each pullet--are smaller than the eggs that the same hen will produce as an older hen.

• “Fart egg” and “oops egg” are terms for tiny eggs that quickly pass through the oviduct without reaching full size.

• Shell-less eggs are released before they have time to develop a shell. They may have membrane holding them together or just be loose yolk and white.

• Double eggs or “egg in an egg” are created when an egg with a shell is encased by the next egg in the oviduct and a shell is produced over the outer egg as well.

• Double yolkers may have a normal amount of egg white with two or more yolks. In the shell, the egg may be unusually large.

• Shell color is only “skin deep”-- the eggs inside are the same as eggs of other colors.

• The shell color intensity of eggs laid by one hen can vary from time to time, with an occasional darker or lighter eggshell.

• While most eggs have a slight sheen to the shell, some breeds or individual hens tend to lay eggs with a chalkier texture.

Chicken-and-egg behavior

• Most hens will lay eggs in the same nest box as flockmates, so it’s not necessary to have a nest box for each hen.

• Some hens like to lay their eggs in private and others will join their sisters in the nest box. Often two or three hens will crowd into one box while another nest box remains empty.

• Sometimes a hen will sit on previously laid eggs and add her egg to the clutch. Another might prefer to sit in another area and deposit one egg by itself.

• Often a hen will sing “the egg song” before or after she lays an egg.

Some will sing during the process of laying. It is a cheerful song that seems to be a proud announcement.

• Chickens learn by example, so a fake or real egg left in a designated nest box may encourage hens to lay there instead of on the floor or outdoors.

• Unconfined hens may lay eggs anywhere outdoors if they don’t want to return to the nest box. Sometimes a free-ranging hen will go missing and reappear weeks later with a parade of chicks.

• Chickens like to eat eggs, even their own. An egg that gets accidentally broken will likely be eaten by one of the chickens.

If you occasionally find pieces of shell or egg yolk in the nest box, it’s usually nothing to be concerned about.

• Some chickens become habitual egg-eaters that break eggs open and eat them. An egg-eater should be culled from the flock if you wish to have eggs for the kitchen.

Not only will that chicken continue to eat eggs, but others will learn from watching and you may end up with several egg-eaters.

• Holes in eggs and cracked eggs do not necessarily mean there is an egg-eater in the flock.

A hen can accidentally crack an egg in the nest when she sits down or adjusts the nest to lay her own egg.

Sometimes curiosity or boredom leads a chicken to peck at an egg without the intention of eating it.

• Chickens can be fed their own or other eggs either raw or cooked.

Eggs provide protein and the calcium in the shell is beneficial for laying hens. A potato masher can be used to break boiled eggs into pieces of egg and shell.

• Empty eggshells from the kitchen can be fed back to chickens as a calcium supplement without concern for developing egg-eaters.

However, to be safe, crushing the shells or running through a blender is a good idea.

Chicken birds and bees

• Baby chickens are chicks. Female chickens are pullets until they’re old enough to lay eggs and become hens.

• Male chickens are called roosters, cocks or cockerels, depending on the country you’re in.

• A rooster announces to a flock of chickens that he’s found food with a “took, took, took.” But the hens don’t pay attention if they already know that there is food around.

• Roosters perform a little dance called ‘tidbitting’ in which they make sounds (food calls) and move their head up and down, picking up and dropping a bit of food.

Researchers have found that females prefer males that often perform tidbitting and have larger, brighter combs on top of their heads.

• A female chicken will mate with many different males but if she decides, after the deed is done, that she doesn’t want a particular rooster’s offspring and can eject his sperm.

This occurs most often when the male is lower in the pecking order.
• Scientists think that the rooster’s wattle–the dangly bit beneath his beak–helps him to gain a hen’s attention when he is tidbitting.

• The only reason a rooster would be required with a flock of hens is to fertilize eggs.

As a side job, a good rooster also serves as a watchman, warning his hens of predators and other dangers. He also seeks out food for his harem.

• Even with a virile rooster in residence, not all eggs will be fertile.

Some hens just don’t interest a rooster and others never get caught. And yes, often, roosters will have favorite hens that get most of their attention and others remain unnoticed.

• Hens do not have an estrus cycle. They can mate and develop fertile eggs at any time.

• Sperm can remain viable in the hen’s oviduct for three to four weeks, so one mating will fertilize numerous eggs.

Brooding and hatching

• A broody hen of any breed can be used to hatch eggs and raise chicks from other hens of any breeds.

• A broody will sit on any eggs, whether or not they are fertile and regardless of who laid them.

To gather a suitable clutch of eggs, she will not only lay her own eggs but may roll other hens’ eggs into her nest.

• While a hen is brooding, you can remove daily any extra eggs she gathers into her clutch.

Drawing pencil “equator” lines around the eggs you want her to brood will help with identification.

• A setting hen will usually leave the nest at least once a day to eat, drink, and defecate.

The eggs are not in danger of cooling off too much during a normal foray into the coop or run.

• Typically, chicken eggs hatch about 21 days from the beginning of incubation or nesting by a broody hen.

A few days early or late is not unusual, and some breeds lean toward earlier or later hatches.

• Not all fertile eggs will develop into embryos. Some never develop due to egg deficiencies or temperature fluctuations.

• Not all chick embryos will successfully hatch. They can die any time before hatching, even after pipping a hole in the egg.

• If a broody hen has pushed an egg out of the nest, she probably knows something is not right with that egg or embryo.

In the kitchen

• A normal fresh egg has a yellow yolk, a layer of thick albumen (egg white) surrounding the yolk, and a thinner layer of albumen surrounding that.

• At opposite sides of the yolk are two chalazae, short white twisted strands of albumen that anchor the yolk to the white. A large chalaza does not indicate embryo development.

• Every egg yolk has a white disc called a blastoderm. It is usually visible but may be very pale.

In an infertile egg, the blastoderm is solid white. In a fertile egg, the disc has a faint or distinct ring that makes it look like a donut or bulls-eye.

• Fertile eggs are completely edible.

In fact, some people consider fertile eggs more nutritious than infertile eggs, but scientific research does not confirm this.

• Fresh fertile eggs collected daily will not have embryos in them.

Embryos do not begin to develop unless the eggs are in a favorable warm environment under a broody hen or in an artificial incubator.

• The yolk of a chicken egg may be any shade from pale yellow to orange, depending on what the hen has eaten.

The color is usually consistent if hens are fed only one type of feed, but foraging hens and those fed kitchen scraps will often produce a variety of yolk colors.

• The egg yolk or egg white may have red or brown specks in it.

These “blood spots” and “meat spots” are harmless bits of tissue and are allowed in commercial Grade B eggs.

If they look unappealing, the spots can be removed with a spoon or knife before cooking.

• An eggshell has a protective coating that prevents bacteria from entering the egg. To retain this coating, eggs should not be washed until just before use.

• Some eggs are soiled with blood from minor tissue damage or mud or feces from the nest box. This can be wiped off carefully; the shell should be thoroughly dried.

• If you aren’t sure how old an egg is, you can submerge it in water.

The freshest eggs will remain at the bottom of the container, while old eggs will float.

Floaters should either be discarded or opened far from your nose.

Did you Know? List of Facts about Chickens

Facts are statements which are held to be true and often contrasted with opinions and beliefs.

Our unusual and interesting facts about Chickens, trivia and information, including some useful statistics about animals will fascinate everyone from kids and children to adults.

Interesting Facts about Chickens are as follows:

Definition: The chicken (Gallus gallus domesticus) is a domestic fowl bred for meat or eggs.

Gallinaceous birds are described as heavy-bodied ground-feeding domestic or game birds including Turkeys, grouse, quail, pheasant and chickens.

The chicken, Gallus gallus domesticus, is a domestic subspecies of the red junglefowl, a member of the pheasant family that is native to Asia. Genetic studies have found that the grey junglefowl also contributed to the chicken’s evolution.

The chicken is the most populous bird in the world. With 50 billion chickens in the world, there are more of them than any other bird species.

Over 50 billion chickens are reared annually as a source of food, for both their meat and their eggs

Chickens farmed for meat are called broiler chickens, those farmed for eggs are called egg laying hens

It is believed that chickens were first domesticated over 10,000 years ago in the far east

Males chickens are referred to as "roosters" in the United States and Canada and "cockerels or cocks" in the United Kingdom.
Castrated roosters are called capons

Female chickens, over a year old, are called hens, and younger females are called pullets

Lifespan between 5 - 10 years, however, a free range meat chicken will usually be slaughtered at about 14 weeks

Domestic chickens are not capable of long distance flight unlike birds

A group of chickens is called a flock

Coxcomb - A coxcomb is the the fleshy red crest on the head of the domestic fowl

The direct ancestor of the domestic chicken is believed to be the Red Jungle fowl (Gallus gallus) which is a tropical member of the Pheasant family

Eggs contain just 85 calories each but are packed with nutrients including protein, zinc, iron, iodine and vitamins A, D, E and some B vitamins.

General dietary recommendations from the American Heart Association are that adults eat no more than 3-4 eggs yolks each week

Bird Flu is a virus known as Avian Influenza. Avian influenza (a.k.a. bird flu) is extremely contagious and can make chickens very sick and kill them.

The highly pathogenic form of the disease can kill off 90 to 100 percent of birds in a flock in just 48 hours.

"Which came first, the chicken or the egg?"
Answer: Recent studies show that the chicken came first, because of the methodology of evolution. An egg cannot occur unless a a chicken is able to lay that egg

Chickens are the closest living relative of the dinosaur called the tyrannosaur

Ameraucana and Araucana can lay eggs colored in shades of green or blue, depending on the breed

Chicken are pretty fast. The chicken can travel up to 9 miles per hour when it wants to.

Chicken language has real meanings. The birds give different alarm calls depending on which type of predator is threatening them.

There are more chickens on Earth than there are humans.

Chickens can cross breed with turkeys. The result is called a 'Turkin'.

There are four cities in the United States that have the word "chicken" in their name: Chicken, Alaska; Chicken Bristle, Illinois; Chicken Bristle, Kentucky; and Chicken Town, Pennsylvania.

The greatest number of yolks ever found in a single chicken egg was nine!

Chickens experience REM (rapid eye movement) sleep.

The chicken is the closest living relative of the tyrannosaurus-rex.

In Gainesville, Georgia, (the chicken capital of the world), a local ordinance makes it illegal to eat your chicken with a fork.

The waste produced by one chicken in its lifetime can supply enough electricity to run a 100 watt bulb for five hours.

China has the most people in the world, and also has the most chickens.

There are over 3,000,000,000 chickens in China! That's 3 billion chickens!

The United States has only 450 million.

The longest recorded distance flown by any chicken was 301.5 feet.

The record for laying the most eggs in one day was seven.

There are more chickens in the world than there are of any other domesticated bird. In fact, there's more than one chicken for every human on the face of this earth.

Chickens can fly, but not for long. The longest recorded flight of a chicken is only thirteen seconds.

A chicken will lay bigger and stronger eggs if you adjust the lighting in their cages to make them think each day is 28 hours long, instead of 24.

Chickens eggs come in colors sometimes, (other than white and brown). Some breeds lay eggs in shades of blue or green. Ready-made Easter Eggs!
The fear of chickens is called 'Alektorophobia'.

Laid head to claw, all the chickens consumed from KFC worldwide would circle the Earth at the equator 11 times.

This bird was probably first domesticated for the purpose of cockfights, not as food.

Chickens aren’t completely flightless—they can get airborne enough to make it over a fence or into a tree.

These birds are omnivores. They’ll eat seeds and insects but also larger prey like small mice and lizards.

There are dozens of chicken breeds, such as the Dutch bantam, leghorn and Rhode Island red.

Chickens are sometimes kept as pets and can be tamed by hand feeding, but roosters can sometimes become aggressive and noisy, although aggression can be curbed with proper handling.

Some have advised against keeping them around very young children. Certain breeds, however, such as silkies and many bantam varieties are generally docile and are often recommended as good pets around children with disabilities.

Some people find chickens entertaining and educational, while others just find them tasty!
